1-10. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS.
The following provides the location and a brief description of the operation and purpose of the 200/600 GPM
Pump. Refer to Figure 1-1.
a.
Priming Vent Drain Tank (1). Collects fuel and vapor during priming of the 200/600 GPM Pump.
b.
Starter Generator (2). This unit is mounted to the gearbox of the engine and consists of several windings. It is
constantly engaged with the gearbox of the engine. While cranking the engine, all starter coils in the dc starter-
generator are used for maximum torque output. When the engine runs, the main starter coil is disabled by
external means to convert unit for generator operation.
c.
Exhaust Extension (3) and Muffler (4). Exhaust extension and muffler are used to reduce the noise level of the
engine. Exhaust extension is removed and stored inside 200/600 GPM Pump during travel and storage.
d.
Control Box (5). The control box is mounted to the side of the 200/600 GPM Pump It consists of a box, a door
assembly, the components panel and most of the controls and indicators that are necessary to operate and
monitor the 200/600 GPM Pump.
e.
Battery and Battery Tray (6). A 24 vdc battery provides power to start the engine. Battery is also used to
operate the electric winch and various electrical controls and indicators and is constantly recharged by the
generator when engine is running. Battery is mounted in the battery box which swings outward, away from
enclosure, for replacement or servicing of the battery.
f.
200/600 GPM Fuel Pump (7). 200/600 GPM fuel pump is driven by the engine output shaft thru a gear reducer.
Its purpose is to pump fuel from storage devices to airplanes, helicopters, trucks, tanks, etc., and from bulk fuel
vessels; i.e., railroad tank cars, fuel tankers, boats, etc., to system storage tanks.
g.
Ball Valve (8). A ball valve at the discharge side of the 200/600 GPM Pump permits isolation of the fuel in the
suction side from the discharge side. The purpose of this valve is to prevent flow back of fuel from the
discharge side of the system to the suction side. This could occur when the fuel tanks of the vehicles being
serviced are at a higher altitude than the supply tanks.
h.
Wheels (9). There are four wheels located on the 200/600 GPM Pump that are used for moving or
repositioning the pump.
i.
Winch (10). Winch is electrically operated by the battery and/or from another vehicle when slave cable is
deployed. Winch is useful to move 200/600 GPM Pump over short distances.
j.
Engine (11). The engine is mounted to the engine mounts on the frame. Its purpose is to drive the 200/600
GPM fuel pump. It consists of a compressor, gearbox, turbine wheel, enclosure, combustion assembly and
electronic sequencing unit.
